Canal between ears helps alligators pinpoint sound
March 28, 2014
Alligators can accurately pinpoint the source of sounds. But it wasn't clear exactly how they did it because they lack external auditory structures. Now, a new study shows that the alligator's ear is strongly directional because of large, air-filled channels connecting the two middle ears. This configuration is similar in birds, which have an interaural canal that increases directionality.
